I should have taken pictures of that while it was out too. Unfortunately all I can provide is a written description unless I find my drawings for the piece parts. The sheet metal that is there is way too flimsy to hold in a crash so I made a box section long enough to pick up the two reinforcing members that run above and below the rear window (and around to the rear of the door). The box reacting against those reinforcements is what provides the load bearing. The piece is made of 4 strips welded together and is about a foot long x 2 in wide by 1/2 in deep. The reinforced nut to hold the strap is welded inside the box. It is all 16 gauge steel because that is what I had laying around. It floats back there so the only alignment is the bolt. I did not want anything welded in place so it could be put back to stock if desired and I thought getting everything straight enough to thread in the bolt once welded in was probably beyond my skill. As it was getting it in was hard enough!
Thankfully it has never been tested 'in anger' but I think that the whole cab would have to deform for it to move a lot, in which case it probably would not be a survivable crash anyway.
